My friend has a 04 3.2 Quattro... The temperature level on the speedo wasn't working, so we bought a spare cluster with intention to unsolder the movement for the temperature and solder it onto the non working part... before this was done, he changed the "chip" over from the old cluster to the new one hoping that the new cluster would install the information and would be an easy swap.. However we didn't know about the coding, now the temperature sensor is soldered on the old clusters... all the dials are working... But now he has a power steering light and no power steering and an abs fault light up... What have we cased by doing what has caused these faults ? he hasn't turned the battery off for several minutes in hope to rest anything, if that happens? Any help greatly appreciated.
